JOHN W. GRAHAM, OF I-IINTON, WEST VIRGINIA.

TYPOGRAPHICAL on LINE-cAsTINe MACHINE.

Application filed May 20, 1915.

To all whom it may concern:

Be it known that I, JOHN W. GRAHAM, a citizen of the United States, residing at Hinton, in the county of Summers and State of est Virginia, have invented certain new and useful Improvements in Typographical or Line-Casting Machines, of which the following is a specification.

My invention relates to typographical or line casting machines such as linotypes of the original construction, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, together with expanding spacers, the composed line brought in contact with the face of a mold, the mold filled with molten metal, to form a line of type or slug against the matrices, which produce the type char acters thereon, and the matrices thereafter returnedto the magazine from which they were originally drawn.

More particularly it relates to that class of machines, having a series of magazines in connection with means, whereby, any magazine of the series may be moved into operative position, and, wherein the magazines are individually removable, and exchangeable, and to that end are each mounted in a rack, in such manner, that any desired magazine can be removed without interfering in any way with any othermagazine of the series, and, wherein the series of magazines are so mounted that the ma chine in its construction may be fitted with only one magazine, and any practical number of magazines may be added as desired,

the construction and housing of the magazines, with their attendant racks, being such, that no change whatever is necessary to add more magazines as desired, and I also provide means to steady and support the magazines in perfect alinement, when in and near the operative position and for this purpose provide guides or rubbing blocks at each end of the racks, which support the magazines, and such rubbing blocks .guide the rack in its line of travel, and I also provide means whereby thatthe magazines when above the operative position, begin to move backward or away from the operator, and are then traveling on a line sub stantially transverse to the line of travel below the operative position, and I also construct the bent arms so that they are of less width in and above the bend, than below Specificatien of Letters Patent.

it, to allow the racks to still rest on the one immediately beneath after they begin to rise above the bend in the arm. It is apparent to those skilled in mechanics, that the racks in and below the operative position are resting, at right angles to the arm on which they are traveling, while those above the point of the bend are not lying at right angles to the arm at the point at which they are engaged with the said arm, but are still lying at right angles with the arm as it is below the bend. It will be further apparent that if the arm above the bend was made as wide as below, the racks would have to maintain a line of rest at right angles with the arm, and to do this the front end of the rack would have to rise up; this feature is overcome by our construction. I also provide a base which travels on the said bent arms and supports the racks and magazines. It is fitted with nuts, which engage the screws to raise and lower the magazines, and I also provide hand and power means for raising and lowering the base, and its supported racks and magazines.

In the drawings I have shown my invention applied to a linotype machine, but it will be obvious that it may be applied to other machines, and many changes and variations made therein, without departing, from the spirit or principle of this inve tion.

Generally speaking I desire to be understood that I do not limit myself to any specific form or embodiment, except, in so far as such limitations are specified in the claims.

Referring to the drawings, Figure 1 is a side View of a portion of a linotype machine, having my invention applied thereto. Fig. 2 is a rear view of the supporting arm A having attached, the shaft and bevel gears which operate the screws used in raising and lowering the magazines. Fig. 3 shows the lever used in operating the power raising and lowering device. Fig. 4c shows the power raising and lowering device. Fig. 5 shows a section of the front end of a magazine, showing the verge in place, and also shows the trip finger and part of the attached key rod. Fig. 6 shows a top view of the base B showing the housings which guide its travel, on the arm A, and also shows the pieces B with the holes to en gage the screws to'raise and lower the mag azines. Fig. 7 shows aside view of the base B Fig. 8 shows a view of the base B with a rack B attached, and the magazine M in place. Fig. 9 shows a side view of a section of a rack B, showing the dogs B and the rollers B also showing the sheet iron lining B, in the rack B. Fig. 10 shows a section of a magazine showing the strengthening bars M extended out at their ends to act as stops, working in connection with the dog B to hold the magazines in place, and shows the extended ends tapered at their rear corners so as to slip out freely when the magazine is to be removed.

Referring rst to Fig. 1:

The magazines M are mounted in the racks B of which the lowermost rack B is made fast to the base B and so set that when the base B travels upward, or clownward, the magazine M housed in the lowermost rack will come in exact operative position, and each additional. rack is placed on and supported by the rack immediately below, and rests on the rollers B of the said lower rack, whose duty it is to support such rack above and allow the same to move backward, or forward, as the rack travels upvward or downward. The racks B house and support one magazine, and such racksare independent and separate from each other, and the series is so constructed as to be built up on the unit plan, that is the lower rack is fastened tothe web B by any desired means, and when the magazine is placed in o the said rack the machine is then ready for operation as a one-magazine machine. Other racks can be added as desired, as many as the stroke of the screws B can accommodate, in this instance being eight.

A shows the arm which extends back from the main arm A, whose function it is to house and support, the distributing and channel entrance mechanism.

A shows an arm or brace extending from a point near the top of the main arm A, down to the frame of the machine, this brace also acts as a guide for the front ends of the racks B, to keep them in direct line when in or near operative position.

C shows a shaft which extends across both forks of the main arm A, and is shown more clearly in Fig. 2.

C? shows a bevel gear on the shaft- 0, which gear C meshes into the bevel gear 0 on the shaft G which shaft has on its outmost end the hand wheel C for raising and lowering the magazine.

Referring to Fig. 2:

A is a back view of the forked arm which supports the magazines.

A shows the shoulder block made fast to the arm A, and drilled to receive the screws B C shows the bevel gears on the ends of the screws B which mesh into the bevel gears H, on the shaft C.

C shows a bevel gear on the shaft C near its center which intermeshes with the bevel gear C on the shaft C shown in Fig. 4-.

The shaft C has on its other end the bevel friction wheel D C and C are used in connection with the power raising and lowering device, and will be explained in Fig. 4.

Referring to Fig. 3:

Fig. 3 shows the lever E which operates the power lowering and raising mechanism. Ttis forked in one end so as to lie in the slot D in the sleeve D shown in Fig. l, and is pivoted on the pin D so as to allow it to throw either one of the bevel friction wheels 13*, into contact with the friction bevel wheel D The friction bevel wheels D are made fast to the sleeve D which is fitted to the shaft D, by a loose key, which allows the sleeve D to slide endwise, on the shaft D a sufficient distance to engage either of its connected friction pulleys D with the friction pulley D and thereby operate the raising and lowering mechanism in either direction as desired.

7 D is a pulley on the end of the shaft D which shaft and pulley is already on all ma chines of the class described.

Fig. 4 has been explained in Fig. 8.

Referring to Fig. 5, it shows the verge V housed in the slotted bar V and pivoted between the pins V and V and held down at its rear by the spring V thereby causing the front pawl V to hold the matrix in place.

V shows the trip finger engaged with the key rods V by a socket joint. V shows the pin on which the trip finger V is pivoted.

V shows the casting which is slotted to house the trip finger V and also the upper end of the key rod V 7 Referring to Fig. 6, it shows the base B looking down from the top, and showing its attached housings through which pass the forked arms A, and also shows B, castings bolted to the said base, and having threaded holes to engage the screws B Fig. 7 is a side view of the base B shown in Fig. 6. r

Fig. 8 shows the rack B having in it the magazine M, looking down from the top. B are the guide rollers shown side view in Fig. 1. F shows the casting Which houses the guide rollers B and is made fast to the rack B. B shows the rollers which support the rack immediately above the rack of which they are a part. B shows the stop dog shown side view in Fig. 9. The dotted lines in Fig. 8 show the strengthening bars on the. underside of the magazine, two of which are made flush with the magazine at its sides, and two projecting outward and made beveled off so as to act as stops working in conjunction with the stop dogs B to hold the magazines in lace.

Figs. 9 and 10 have been explained in connection with Fig. 8.

In operating the machine any of the magazines of the series can be brought into operative position, by means of the hand wheel C or by power by moving the lever E to the right or left, thus engaging one or other of the friction wheels D, with the friction wheel D on the shaftG". The bevel gear C on the shaftv C operates the bevel gear C, which is fast to the shaft 0, whose attached gears H operate the screws B by means of the connected bevel gears C thus raising or lowering the base B and the magazines which the said base B supports. The arm A guides the travel of the magazines M by means of the guide rollers B, which guide the racks B in which the magazines M are housed.

As previously stated I have shown my invention by way of example and in a preferred way, and it is obvious that many variations and changes may be made therein, without departing from the spirit or principle of this invention.
